Hurt was an understatement. Was it possible to break your butt? Yumi pulled herself onto the branch and crouched rather than sat, tentative of her aching backside. "I'll keep that in mind, thanks Shu!" Less stony? Less power? So was she being too rigid? That was fair, she was unsure of herself and probably tensed up while swinging about. Shu tended to grab with whatever limb was nearest to the branch; Yumi knew she didn't have that luxury but she could still try. 

"I get it! I think... Be more loose, stop trying to force it, right?" She couldn't help but laugh at Shu's question. Her palms ached sure - her backside definitely was sore - but she could keep going. "I'll have some blisters when we're done but that's no big deal. Let's keep going!" Whether she was getting it down perfect or not didn't matter. She was having fun, Shu was having fun, and that was the whole point of the day really. If she managed a new skill then that was just icing on the cake. 

Yumi got back onto her feet and tested her balance. Still good. She looked for the nearest branch to swing and lowered herself back into a squat, inhaling and focusing her eyes solely on the branch. With one big leap she jumped the gap, reaching out and grabbing the branch, holding on and swinging back and forth, building momentum. When she let go she made it to the next branch with ease, and after kicking her legs a few times, the next as well. She managed to make it through three trees before her fingers slipped around a branch and she fell. Barely catching herself on a lower branch she hung there for a moment, giggling and pulling herself up onto it. "See? I've only almost died twice!" She joked, sitting down and waving up to Shu. "I think I'm getting the hang of it! Get it? Because we're... Swinging..."
